      Girimaji et al.26 used constant values of fk in their PANS computation of flow around a circular cylinder. However, the constant value of fk was found to be unsuitable for the current investigations with the large unsteady flow dynamics. Therefore, a spatially and temporally varying fk that is dependent on the local grid and the turbulent ...

      Determine the drag force and drag coefficient of flow around a cylinder. Background: The CSUS subsonic wind tunnel is illustrated in Fig. 1. Air enters the tunnel through the inlet section, passes through flow-straightening screens, and accelerates in the contraction section. Downstream of the contraction is the test section, which is 0.30 m by ...

      This is useful to “migrate” around the cylinder while zoomed in. Save your velocity profiles and your calculations: In the main Fluent window, File-Write-Case & Data. In the Select File window which pops up, the default file name should be “laminar_cylinder.cas.gz”, as previously entered. OK to write the file onto your directory.

      The Reynolds number relates the flow through a straight pipe and is given by Equation 1, where dtube is the inner diameter of the tubing U is the fluid velocity. However, since the experiment involved flow through a pipe that was curved around a cylinder of varying radii, the Reynolds number was not applicable. Equation 1
